DIRECT CURRENT CONTROL WITH LOW E-M EMISSION

摘要

A switching control circuit includes driving a flow of direct current through an at least partially inductive load. The switching control circuit is adapted for adjusting a control current in order to activate and/or deactivate a flow of current to a load terminal. The system comprises a timer element for initiating at least one timed adjustment of the control current during activation or deactivation of the flow of current through a first semiconductor switch of the circuit so as to anticipate a state change of a component of the switching control circuit. The controller is adapted for determining a timing for the timed adjustment in a predictive manner. A method employs the various features of the switching control circuit.
